The final trailer for “X-Men: Days of Future Past” has debuted, and the clip spotlights the critical role in the narrative played by Hugh Jackman’s Wolverine.

“I was sent here for you, from the future,” Jackman’s Logan says to a younger Charles Xavier, played by James McAvoy.

“Could you give me that one more time please?” the disheveled Xavier asks with a laugh.

Mutant fans can check out the clip promoting the director Bryan Singer’s film, which is set to arrive in theaters May 23, below.

Adapted from one of the beloved comic book story lines conceived by Chris Claremont, “X-Men: Days of Future Past” stars actors from Matthew Vaughn’s 2011 prequel “X-Men: First Class,”and the original “X-Men” trilogy, which launched in 2000 with Singer’s original “X-Men” and arguably ushered in the current golden age of comic book films.

“Future Past’s” expansive cast includes McAvoy playing the younger Xavier, with Michael Fassbender and Ian McKellen playing Magneto. Also featured are Jennifer Lawrence as Mystique, Nicholas Hoult as Beast, Page as Kitty Pryde, Ashmore as Iceman, Halle Berry as Storm, Omar Sy as Bishop and Evan Peters as Quicksilver.

“Game of Thrones” star Peter Dinklage joins the ensemble as Bolivar Trask, the mastermind who initially creates the Sentinels, robots who in the future seek to drive mutants into extinction.

In Singer’s film, the X-Men ultimately hit upon a plan to prevent the bleak future — by projecting Wolverine’s consciousness back in time into the body of his younger self, they hope to unite friends-turned-adversaries Xavier and Magneto and avoid the events that will trigger the dystopia.

In an interview with Hero Complex, Singer pointed out one unlikely inspiration for “X-Men: Days of Future Past”: Schrodinger’s cat.

“There’s a theory about things: Until they’re observed, they haven’t really quite happened yet … it’s called a superposition in quantum mechanics,” he explained. “If you put a poison that may or may not release inside a box with a cat, until you observe the result, the cat is both alive and dead at the same time. The outcome hasn’t happened yet, so you can muck about in the past, but until you return to observe the future, it doesn’t take hold. That’s called collapsing the superposition.

“I applied this notion to our story line, and it really helped me create a narrative where both the past and future can coexist at the same time.”
